Having the same issue with my 95 Lumina. First determine if its on the left or right side, then determine if its the wheel bearing or a bearing in the drive axle. If theres clunking associated with the humming (like mine) then its most likely the latter. Is cheaper to just replace the entire drive axle too by the way

The humming noise can be in your exhaust system. The exhaust will heat up and seal the area where there can be a leak. The hot exhaust will cause the noise to decrease.

Yes a humming out back could be a fuel pump failing. I have gone through 2 in my 1993 Century - 150 k miles - They have to drain and drop the tank to repair
